People with diabetes may need to monitor their blood sugar more closely when doing high-altitude activities like hiking or skiing, according to a recent study. These findings were published in the Society’s Journal of Clinical Endocrinology and Metabolism. Doctors often recommend exercise for people with diabetes due to its many benefits. It can improve heart health, insulin sensitivity, and quality of life. However, exercise can also cause hypoglycemia (dangerously low blood sugar) in people with diabetes during and after a workout. If a person’s BS drops to really low levels, quick action is needed as they can have seizures, become unconscious or even die.
